How to unlock speed limit on ebike

As an electric bike (pedelec) motor manufacturer, many cyclists inquire about how to remove the speed limits on their e-bikes. This article will be divided into two parts. 1. What factors influence the speed of an e-bike? 2. Methods for unlocking the speed limits on various TRUCKRUN display screen models.

Removing the speed limit doesn't increase motor power:

There are various reasons for wanting to remove an e-bike's speed limit, such as reaching your destination more quickly or meeting specific riding preferences. It's important to note that removing the speed limit doesn't provide additional power to the motor. Instead, it allows the motor to maintain power output even after the e-bike reaches a certain speed.

Rider and bike weight:

The impact of weight on speed is undeniable. Heavier riders typically experience relatively slower speeds. To enhance your speed, consider minimizing the weight carried on the pedelec, which may include reducing luggage or cargo.

Motor power:

The size of the motor's power significantly determines the maximum speed. Higher-powered motors generally have a higher potential speed. For instance, a 100kg rider with a 250W motor can achieve speeds of up to 30 km/h with the speed limit removed, while a 350W motor can reach 35 km/h, a 500W motor can reach 42 km/h, and a 750W motor can reach 50 km/h.

Tire pressure and type:

Proper tire pressure and tire type have a direct impact on riding speed. Ensure that your tire pressure is close to the upper limit specified on the tire, which can effectively enhance your riding speed. Narrow tires are generally faster than wide tires, and slick tires are faster than off-road tires.

Cyclist's physical condition:

The rider's physical fitness and riding posture also affect the e-bike's speed. Adopting the right riding posture and employing proper riding techniques can help increase speed. Lowering your body, wearing tight-fitting clothing, and reducing wind resistance can be effective in achieving higher speeds.
